Introduced here are carrier assemblies designed to address the limitations of conventional carrier trays. A carrier assembly can comprise a primary injection-molded component having a deck area for receiving semiconductor components and a secondary injection-molded component that is secured to the deck area of the primary injection-molded component. For example, the secondary injection-molded component may be overmolded on the deck area of the primary injection-molded component. The secondary injection-molded component may have a tacky upper surface that facilitates securement of the semiconductor components to the primary injection-molded component.

The present invention relates to the field of forming technologies for rubber sealing ring blanks, and more particularly to an automatic forming method and device for a rubber sealing ring blank. A cutting blade is fixedly connected to the surface of a blank forming assembly; an equipment body II is fixedly connected to a sliding table die set; a supporting rod II is fixedly connected to the surface of the equipment body II; a blank box is fixedly connected to the inner side surface of the supporting rod II; and a blank spool is fixedly connected to the tail end of a long blank strip. The method and device disclosed by the present invention have the advantages that the automation degree is high, and the long blank strip conveyed from the blank spool passes through guide wheels and a guide groove and is automatically pressed into a ring through the combined action of the blank forming assembly and the cutting blade. According to this patent technology, feeding is performed by means of continuous introduction of the blank strip; and automatic formation of the blank ring is achieved through the action of an automation assembly. Except for a process of replacing the blank spool after the long blank strip of the blank spool is used up, the other processes are all completed by the machine, such that the automation rate is high.

A system for additive manufacturing a medical device, the system comprising a first dispensing system, a second dispensing system, a deposition apparatus, and a deposition substrate on a surface of which the deposition apparatus is configured to deposit at least one elastomeric material into a filament. The deposition apparatus receives the at least one elastomeric material from the first and second dispensing systems in proportions effecting a desired property in the medical device. The deposition apparatus may comprise heating and/or cooling elements, a sonic vibration module, and/or a pneumatic suck-back valve. The deposition substrate may have a configuration corresponding to a desired shape of the medical device and is configured to rotate and/or translate relative to the deposition apparatus. The system comprises a controller configured to control the deposition.

A glass run channel includes a header and one or more inserts molded into the header. The header includes an upper header wall, an outer header wall extending from the upper header wall, and an inner header wall extending from the upper header wall opposite the outer header wall. The inserts include an upper insert wall provided within the upper header wall, an insert body extending from the upper insert wall and provided within the inner header wall, and a hook wall extending from the insert body. The header fully surrounds the inserts. A portion of the header surrounding the one or more inserts defines a hook for a sunshade.

A granular material for a fused deposition three-dimensional printer that enables a flexible molded object to be manufactured with high precision. A granular material for a fused deposition three-dimensional printer is provided. The granular material is formed of a thermoplastic elastomer, and the thermoplastic elastomer has, at at least one of the measurement temperature of 120 to 270 C., a loss tangent tan of 0.40 or more and a loss modulus G of 11000 Pa or less, which are measured with a rotary rheometer having a pair of parallel plates with a diameter of 20 mm and a measurement gap of 1.3 mm at a frequency of 1 Hz.

A fully-automatic production line and an automatic production method for rubber sealing rings. The fully-automatic production line includes a ring forming area, a molded vulcanization area, a flash removal area, a two-stage vulcanization area, an online detection area, a packaging and labeling area, and a control room. An automatic production line for rubber sealing rings involves the steps of loading and transferring, molded vulcanization, flash removal, second-stage vulcanization, packaging and labeling, and the like. The fully-automatic production line solves the technical problems in the prior art that the production of rubber sealing rings fails to adopt the molded vulcanization process, and meanwhile the specifications of the produced rubber sealing rings are single.

The mat of the present invention includes a main body integrally formed by a plastic material. The main body at least has a first surface and a second surface adjacent to the first face. The first face and the second face have different surface physical characteristics. The first surface and the second surface are shaped into a third surface and a fourth surface respectively. The third surface and the fourth surface have a substantially same surface physical characteristic. An angle between the third surface and the fourth surface outside the main body is a specific value.

An ear plug includes an elongated body sized and shaped to be partially inserted into an ear canal of a wearer, in which the body includes a negative Poisson's ratio (NPR) polymer foam material having a Poisson's ratio of between 0 and 1. A mouth guard includes an arc-shaped element sized to be received into a mouth of a wearer. The arc-shaped element has an outer wall, an inner wall, and a biting wall connecting the outer wall and the inner wall. The outer wall, the inner wall, and the biting wall define a channel that is sized to receive upper teeth of the wearer or lower teeth of the wearer. The outer wall, the biting wall, or both includes a negative Poisson's ratio (NPR) material having a Poisson's ratio between 0 and 1.
